The present study analysed the taxonomic status and phylogenetic relationships of two species of xiphidiocercariae of the 'microcotylae' group, Cercaria pugnax La Valette St. George, 1855, from Viviparus viviparus (Linnaeus) in the Ukraine and Cercaria helvetica XII Dubois, 1928 from Bithynia tentaculata (Linnaeus) in Lithuania. Molecular phylogenetic analyses based on sequences of the ITS2 reg...

This manuscript describes the daughter parthenitae (sporocysts) and cercariae of two species of renicolid xiphidiocercaria that infect the California horn snail, Cerithidea californica, which serves as first intermediate host for a diverse and ecologically important guild of digenean trematode parasitic castrators. The two species described here have previously been considered to be a single mo...

background: in this study the haemolymph components of infected and none infected lymnaea gedrosiana with xiphidiocercaria larvae was compared. methods: five hundred fifty lymnaea snails were collected from ilam and mazandaran prov­inces, iran, during 2008-2009. the snails were transported to the lab at tehran university of medi­cal sciences and their cercarial sheddings were studied. haemolmyp...

BACKGROUND In this study the haemolymph components of infected and none infected Lymnaea gedrosiana with xiphidiocercaria larvae was compared. METHODS Five hundred Fifty Lymnaea snails were collected from Ilam and Mazandaran provinces, Iran, during 2008-2009. The snails were transported to the lab at Tehran University of Medical Sciences and their cercarial sheddings were studied. Haemolmyphs...

Aedes albopictus larvae were exposed, either individually or in groups, to different concentrations of xiphidiocercariae of Haematoloechus sp. for parasitological studies. It was observed the acute lethal effect and some aspects of the host-parasite relationship, such as delay or progress in the host life cycle, the number and location of the metacercariae in the host, adult host malformations ...
